FUSE-BOX.

Specification of 'Letters Patent.

Patented Sept. 8, 1908.

Application filed April 8, 1907. Serial No. 366,908.

To all whom 'it may concern? l Be it known that I, HARRY P. MOORE, of Newburyport, county of Essex, State of Massachusetts, have invented an Improvement in Fuse-Boxes, of which the following description, in connection with the accompanying drawings, isa speciiication, like characters on the drawings representing like parts.

This invention relates to fuse-boxes, and while valuable 'tor nearly all such boxes, it is particularly valuable for boxes used with electric currents of high voltage or in dangerous places, such as boxes used with transtormers. Such l'use boxes are frequently placed on poles and other places which are dangerous and inconvenient oiI access and exposed to the weather. lln exaniining or renewing fuses in the boxes hitherto in use both hands of the lineman are o'l'ten required and it the fuse case is wet or there is any defeet in the wiring of the box or the lineman is in the least careless, accidents are liable to occur and often have occurred.

Hy invention has for its object the construction of a fuse-box much easier to install than those hitherto in use, and one in which the fuse may be examined and renewed with the use of one hand only, and with little or no danger of receivingr a shock.

My invention has other advantages which will be readily observed.

To accomplish these results my fuse-box is so constructed that the fuse may be withdrawn and replaced without opening the box or separating its component parts; also, it is provided with fuse-supports, contained within it, which are electrically connected with the circuit wires, and with an end opening so disposed with respect to the fuse-supports as to permit of the withdrawal and replacement of a fuse; and is provided with one or more rotatable or otherwise adjustable members, forming component parts of it, each having an opening for a circuit wire, so arranged that the turning of said member or members will change the positions ot the openings to adapt themto receive the circuit. wires coming from different directions.

Figure 1 shows in plan view a. fuse-box embodying this invention. Fig. 2 is a longitudinal section oi' the fuse-box shown in Fig. 1. Fig. 3 is a longitudinal section of the fuse-box taken on the dotted line 3 3, Fig. 2, the means for removing or replacing the fuse being omitte'd. Fig. 4 is an end view of the fuse box. Fig. 5 is a cross section o'll the fusebox taken on the dotted line 5 5, Fig. 3. Fig. 6 is a longitudinal section ol a modiiied form of fuse-box to be relerred to. Fig. 7 is a view showing in front elevation and partial section another ineditied i'orm oi' `fuse-box.

The fuse-box comprises a cylindrical or other shaped case, and, herein shown, said case is composed of a tubular cylindrical intermediate portlon a, internally screw thread- `ed at each end and two cylindrical end portions Z) and c externally screw-threaded at one end adapting them to be screwed into opposite ends of the intermediate portion. The intermediate portion is intended to be securely fastened to a pole or other support, and is, therefore, secured to a base plate (1, of any suitable construction, which is adapted to be screwed or otherwise secured to such support. The end portion is made as a cylindrical hollow shell, say ot sheet metal drawn to shape, and comprises a. cylindrical side wall and an end wall; and the end portion c is made in a similar manner, although its end wall has a hole through the center of it, shown at c. Usually the box should bev disposed with the opening c in the end portion c at the bottom. Each end portion I) and c has a hole through its side wall at any desirable point and said holes are hereii shown at b2, c2.

The case, constructed as above described or in any equivalent manner, has several advantages, for instance, as the end portions are connected with ,the intermediate portion by serew-threaded connections, they may be turned relative to the intermediate portion and independently of cach other, to bring the holes b2, c2, into positions most convenient for thel attaching ot their respective circuit wires; and the box may bc taken apart for the purpose of repairing any defects in its wiring or for any other purpose, with facilitT and despatch, and without disturbing its lastening to the pole. To secure the end portions in whatever positions they may be caused to occupy, set screws e, c3 may be end thereof or thereabouts, and which is made tubular to fit the interior of the case, and to adapt it to the particular case herein shown, wherein' the end portions are independently rotatable, said tubular lining is. made yintwo parts b4, c4, which abut together at their inner ends, Within the intermediate portionof the case, or approach each other sufficiently to subserve its required functions. The lining is formed with openings b5, c5, coincident with the o enings b2, c2, in the end portions, so that the circuit wires, which are represented at 2 and 3, willn extend through both the Wall of the end portions and through the lining thereof, into the interior of the case.

Within the case and at the opposite ends thereof fuse-supports are' rovided for mechanically supporting the se and for electrically connecting it with the circuit Wires 2, s.

The fuse herein selected is of the inclosed type, comprising a cylindrical shell or case d having end caps d', d of conducting material and containing a yfuse-wire which is connected with said end caps. Consequently the fuse-supports, which areherein employed, are adapted to engage the end caps of said fuse, but if another form of fuse should be selected the fuse-supports would be necessarily modified to adapt them to engage its terminals.

c represents one of the fuse-supports which is contained in the case and which is connected with the end portion c thereof. Said fuse vsupport consists of a short tube,

' -contracted for the greater part of its length lupon a block C8 of insulating material which is contained in the case and which is secured to the end wall of the end ortion c. This block has a hole through 1t, in alinement with the hole through the fuse-support c, and also in alinement with the hole c through the end wall, and provision is thereby made for the withdrawal and replacement of a fuse, that is to say, the fuse may be withdrawn and replaced through thel end opening in the case which is thus provided.

The circuit wire 3, entering the opening c2 is electrically connected with the fusesup port c, and as said support is made of con,

ducting material and engages the end cap of the fuse, said fuse will be electrically connected'with the circuit wire. At the oppo- ..ing fingers projecting from a base, which are adapted' to engage the end ca of the fuse. The fuse-support t is mounte upon a block 67 of insulating material which is contained in the case and which is secured to the end wall of the end portion b. The fuse-support is arranged on the block, in alinement with the fuse-support c6, and With the end opening at the opposite end of the case. A circuit wire 2, entering the opening b2, is electrically connected with the fuse-support b, so that the fuse, -When engaged by sald fuse-sup ort, will be electrically connected with sai circuit wire. A metal plate bs may be used in making this connection. Y

For the purpose of facilitating the withdrawal and replacement of the fuse one of its end-caps may be provided with a screw-threaded pin opposite t e end openingin the case, and a handle e is provided, which is of suitable diameter to project througnhsaid end opening and which has at one 'end a screw-threaded socket adapted'to receive the threaded pin on the end cap and to be thereby Iconnected therewith; By means of said handle the fuse may be withdrawn or replaced.

r If desired the fuse may be locked inengagement with the fuse-supports, in any con-v venient manner,. as for instance, as here shown one of its ends is provided with a latl erally extended pin, 5,'see dotted lines Fig. 2, and one of the fuse-supports is formed with a bayonet slot also shown by dotted lines Fig. 2, which is adapted to receive said pin 5, and

by turning the fuse in its support'it will i become locked. If the fuse-support is constructed Ato firmly engage and hold the fuse, suoli locking means may be omitted.

In practice when the box is on a pole the handle may be left attached to thefuse, and the lineman should attach the new fuse to another handle before climbing the` pole. lf this is done one hand only and no care or skill are required to replace the old fuse with a new one and neither the box nor the fuse need be touched and the operation may be performed even in wet weather or after dark with a minimum of danger. i

Referring to Fig. 6 the shell or case of the box is' composed of two pieces instead of three, which are screwed together, one of which is attached to the base a and the other is movable connected with said fixed member. The movable member is constructed substantially the same as. the member c, shown in Figs. 1 to 5, but the other member h has its opening 71, for the circuit wires at the end.

Referring to Fig. 7 the shell or case is made in one piece which is attached to the base w.
